Here's a response I got from another forum. He is using human reasoning here.
Hi servant :
feeling that you realy want the real answer , I have the honor of giving it
first nothing in the Quranic verses indicated that Adam had to be worshipped by Angles , this bowing down or prostration was made only by the order of God as a sign of honor and respect , to Adam , that new creature who had the advantage over them , that he only had the ability to learn from God , to be able to know the concept of different objects by name , that make all these things while it is a pronounced word , a symbole for , some thing , and but for this ability it was imposible for him to learn , to accept teaches and commandes from God, to comunicate with others by interlocution , learn to read and write , and in breief be fit for the mission God had asigned upon him long before his creation , that is , populating and improving and constructing the planet of earth , discovering it's natural laws , extracting it's hidden treasures , and be a vicegerent on this planet so much suitable for the life of that creature of material requirements , in fact the bowing or prostration meant much respect and glorification , to the great creator who made such a wonderful creature ,........... thank you
